struct CameraIntrinsics (Niantic.ARDK.AR.Camera.CameraIntrinsics)
Where (fx, fy) is the focal length and (px, py) is the principal point location, can be cast into a vector: [fx, fy, px, py].
struct CameraIntrinsics { // properties Vector2 FocalLength; Vector2 PrincipalPoint; // methods static implicit operator CameraIntrinsics (Vector4 v); static implicit operator Vector4 (CameraIntrinsics o); };
